Application nee January 11, 1912. Serial No. 670,598.

To all whom it may concern Be it known that 1, WILLIAM R. NAYLoR, acitizen of the United States, and resident of the city of Providence, inthe county of Providence and State of Rhode Island, have inventedcertain new and useful Improvements in Connectors for Neck-Chains, ofwhichthe following is a specification.

This invention relates to chain connectors, and has for its object toprovide a connector for neck chains and the like, comprising a tubularbody portion and a click or removable member, the latter having twoopposing spring locking arms and a chain engaging eye member all formedof a single piece of spring wire and without the use of solder, by whichconstruction the click may be made of the minimum size and expense andwith the maximum holding power.

With these and other objects in View, the invention consists of certainnovel features of construction, as will be more fully described andparticularly pointed out in the appended claims.

Ofthe accompanying drawings: Figure l'is an elevation of the connectorshowing the tubular body in section with the click member in positiontherein. Fig. 2 is a detail of the click member removed, showing theshape when the wire is first bent. Fig. 3 is an enlarged sectional viewon line 3--3 of Fig. 2 showing the relative position of the members andthe oval shape of the wire in cross section. Fig. 1 shows the clickafter its inner end has been hammered or swaged tightly together toreduce its size and provide a greater spring tension in the oppositearms. Fig. 5 is an enlarged cross sectional view on line 55 of Fig. 41:showing the general shape of the stock at this point after havingundergone the hammerlng or swaging process.

Referring to the drawing 10 deslgnates the tubular body portion which isclosed at one end 11, into which end is loosely secured the eye 12whereby said eye is adapted to readily turn or perform the function of aswivel when connected to the neck chain, not

shown. The opposite end 13 of this tubular member has its edge turnedinward as at 14: providing an annular flange for engaging the click inthe manner presently described.

It is found in practice that connectors of this character should be madeas small and compact as possible and at the same time very strong anddurable so that when the chain is connected together by them there isabsolutely no danger of its coming apart, and so insure the chain andthe valuable pendants which are often worn thereon against loss by anaccidental separation of the connector.

In order to provide a simple, practical and effective click thatpossesses the maximum holding power and yet is capable of beingconstructed of the smallest size and at the minimum expense, I haveconstructed the same of a single piece of substantially halfround oroval spring wire as this shape gives the desired finish to the eye orloop, said wire being doubled near its middle upon it-' self providing amiddle body portion, then having two parts 15-15, and forming a loop 16at the bend. Each of these parts is then bent at 17-17 or doubled backnearly upon itselfforming a pair of opposing spring arms 18-18 havingoutwardly turned manipulating ends19-19 each of said arms being alsoprovided at the bend of said ends witha notch 20 for the purpose ofengaging tghei inwardly turned flange 14: on the tubular The connectormembers in some cases are very small indeed, the hole in the tubularbody portion being exceedingly small, and

in some cases hard to find, and therefore it is greatly to be desiredthat the inner end 21 of the click which is to be inserted into the tubebe made as small as possible to facilitate its ready entrance thereinto.Then again, it is also found in practice that by hammering or swagingthis inner end, in addition to making the same smaller and easier toenter the tubular member, it also imparts to the spring arms 1818greater stiffness and therefor greater power to resist the possibilty ofbecoming disengaged when an unusual strain is brought to bear upon it.With these ends in view I have hammered or swaged the inner end portion21 causing the stock of the outer arms 18 to lap or lay around the ovalshaped stock of the inner members in the manner best illustrated in Fig.5.

By my improved construction it will be seen that the click is made of asingle piece of wire, the loop portions 16 being formed in the middlethereof and the middle body portion being provided with two spring armsset directly opposite 'each other, whereby each arm assists in holdingits opposing arm 7 inengagement with the lip 14 ofthe tubular 7 having aswivel eye connected thereto, the opposite end of said body having itsedge member when the click is inserted therein.

Then again by my improved construction as the eye and the spring armsare formed integral with the rest of the member there is no necessityfor the use of solder in its construction, the use of solder being,as iswell known, detrimental to the practical construction of such devices,as the heat has a tendency to draw and destroy the temper of thesprings.

I claim: 1. In a chain connector, the combination with a tubular bodyhaving an open end surrounded by a flange, of a click formed of a singlepiece of wire bent upon itself at its middle to form a loop at the bentend and providing a middle portion formed of two parts, each of saidparts being again bent upon themselves to form spring arms to engagesaid flange, the wire at said last mentioned bends being compressedtogether to increase the resiliency of said spring arms, the outer endsof said spring arms having outwardly turned 'manipulating ends.

with a tubular bodyclosed at one end and turned inward to form a flange,of a click copies vo1! this patent may be obtained for five cents each,by addressing Washington, I). 0.

2. In a chain connector, the combination formed single piece of wiredoubled at its middle upon itselfforming a loop at the end and providinga middle body portion forming two parts, each of these,

parts being again doubled back nearly upon:

form a loop at the bent end and providing a middle portion formed of twoparts, each of said parts being again bent upon themselves to formspring arms to engage said flange, thewire at saidlast mentioned bendsbeing compressed together to increase the resiliency of said springarms, the outel. ends of said spring arms having outwardly I turnedmanipulating ends. 7

In testimony whereof I affix my'signature in presence of two witnesses.Y
